Westfield Reliability Project

Eversource is proposing to construct a new transmission line and a new switching station in Westfield, Mass. This upgrade is one of a group of projects designed to improve the reliability of the electric system serving the Pittsfield - Greenfield area, both today and in the future.

At Eversource, we're always working to serve you better. The new overhead line would be installed on existing structures along Eversource’s right of way from the Pochassic Substation (near Oakdale Avenue in Westfield) to the Buck Pond Substation (near Medeiros Way in Westfield).

We also would construct the new Atwater Switching Station adjacent to the existing Pochassic Substation, and make upgrades to the existing Buck Pond Substation – all while remaining on Eversource property.

Massachusetts Department of Public Utilities (DPU)

This project requires approval from the DPU through the Section 72 and Chapter 40A application process. See the Westfield Petition - Initial Filing 4-17-18 (large file: 840 pages). The regulatory process also requires approval from local, state and federal permitting agencies, including environmental agencies.

The public and other interested stakeholders were given the opportunity to participate in the siting process through a DPU-sponsored public hearing, by submitting written comments to the DPU, as well as by seeking to either intervene as a party or to participate as a limited participant in the DPU proceeding.

The public hearing was held on August 13, 2018, in the South Middle School Auditorium in Westfield. Owners of property abutting and near the project were informed of the public hearing date and encouraged to participate.

To learn more about the siting process and how to participate, visit the DPU website.


We are engaging town officials, residents, businesses, community groups and other stakeholders through municipal briefings, an open house and meetings – answering questions and listening to concerns about the project.

We will continue these outreach efforts as the project proceeds through the siting process and into construction.
